I am trying to digitize a scanned map that appears to be in the Alaska Series E projection. I have also seen this referred to as Modified Transverse Mercator. While this projection is listed as supported by ArcGIS, I can't seem to find it when changing the coordinate system in Data Frame properties. Has anyone worked with the Alaska Series E projection and how do you get it to project properly in ArcMap? I am running ArcGIS 10.3 and I have an Advanced license.

ArcGIS entry for Alaska Series E: http://help.arcgis.com/EN/arcgisdesktop/10.0/help/index.html#/Alaska_Series_E/003r0000001m000000/

Alaska E has two differing definitions if I remember correctly. You need the post-1973 definition I assume. Pre-1973 data may be on a different system although named the same (Alska Series E is the common name).

This link gives you some of the information you need to define the projection. Page 73 strangely enough. As I say, the meridians switched in ~73 so be careful.

From the ESRI help, I can see it is not predefined in Arc 10.3.

Page 64 of this book appears to have the information you need to define it. I could not find it on spatial reference either.

EDIT - Here is the information at spatial reference as uploaded as a result of this exchange.
